Respiratory complications of Stevens-Johnson syndrome (SJS): 3 cases of SJS-induced obstructive bronchiolitis

Bronchiolitis obliterans associated with toxic epidermal necrolysis induced by infection: A case report and literature review

Background

Stevens-Johnson syndrome/toxic epidermal necrolysis has a severe impact on patients' eyes, genital mucosa, and many other organs. Bronchiolitis obliterans is a rare complication of Stevens-Johnson syndrome/toxic epidermal necrolysis.

Data sources

We report a case of bronchiolitis obliterans associated with toxic epidermal necrolysis in our department. Furthermore, we examined the patients with bronchiolitis obliterans induced by Stevens-Johnson syndrome/toxic epidermal necrolysis and summarized the clinical characteristics, treatment, and prognosis. Databases available online in English including PubMed, Medline, and Web of Science were consulted.

Results

We report one case and review 23 published case reports. Of the 24 patients, 13 were female, the oldest patient was 59 years old and the youngest was 5 years old. The time of bronchiolitis obliterans onset after Stevens-Johnson syndrome/toxic epidermal necrolysis varied from 5 days to 5 months. Bronchoscopy examination showed ulceration, exudative lesions, occlusion, and inflammation. The CT of lung manifestation included mosaic perfusion, bronchiectasis, consolidation, air trapping, pneumatocele, pleural thickening, lung collapse, larger central airway dilatation, lung overinflation, oligemia, and pneumomediastinum. Most cases indicated pulmonary function tests with obstructive ventilation dysfunction. The prognosis was poor; six of the patients died.

Conclusions

Patients with Stevens-Johnson syndrome/toxic epidermal necrolysis may develop bronchitis obliterans at different stages, so all patients with Stevens-Johnson syndrome/toxic epidermal necrolysis should be followed up for possible respiratory complications.

Rare case of Stevens-Johnson syndrome with bronchiolitis obliterans as a chronic complication

A young girl in her teens presented with fever, rashes and various mucocutaneous symptoms. Flat erythematous macules were seen mainly on the limbs, without blisters or skin detachments. The lips were swollen with crusts and haemorrhage. The oral cavity and pharynx showed ulcerative lesions with exudate. Severe bilateral ocular lesions with pseudomembrane formation and corneal epithelial defects were present. Also, urogenital lesion and gastrointestinal symptoms with frequent haematochezia were observed. Her symptoms and pathological findings were consistent with Stevens-Johnson syndrome. She was treated with prednisolone and methylprednisolone pulse therapy. Her ocular and cutaneous symptoms improved without severe chronic complications. However, 1 month later, she developed dyspnoea, and a pulmonary function test revealed severe obstructive ventilation disorder. After discharge, she was regularly followed up for respiratory complications. High-resolution chest CT performed 9 months after onset revealed mosaic perfusions and bronchiectasis, consistent with bronchiolitis obliterans.

End-Stage Respiratory Failure Secondary to Bronchiolitis Obliterans Syndrome Induced by Toxic Epidermal Necrosis, Also Known as Lyell Syndrome: A Case Report

BACKGROUND

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but serious dermatologic diseases. They can be associated with systemic manifestations such as bronchiolitis obliterans syndrome (BOS). SJS/TEN-induced BOS is associated with a poor prognosis, and no guidelines exist regarding its management. Several case reports have described the association between SJS/TEN and BOS, with few patients undergoing lung transplantation as a last resort therapy. Unfortunately, in the published reports, none of the transplanted patients were observed for a long period of time after the transplantation; therefore, the long-term mortality as well as the risk of recurrence of BOS could not be inferred from these reports.

CASE REPORT

We present the case of a young patient diagnosed with SJS complicated by BOS and end-stage respiratory failure refractory to corticosteroid therapy. She underwent bilateral lung transplantation with an outstanding outcome at 5-year follow-up.

CONCLUSION

SJS/TEN-induced BOS might have a favorable evolution and long-term outcomes following lung transplantation. However, prospective studies are needed to confirm this finding.
